Function dump_node 

pub fn dump_node(
    code: &[u8],
    node: &Node<'_>,
    depth: i32,
    line_start: Option<usize>,
    line_end: Option<usize>,
) -> Result<()>

Dumps the AST of a code.

Returns a Result value, when an error occurs.

Errors

Propagates any std::io::Error produced by the color-aware writer that backs stdout (broken pipe, write failure, …).

Examples

use big_code_analysis::{dump_node, tree_sitter, LANG, Node};

let source = b"int a = 42;";
let mut parser = tree_sitter::Parser::new();
parser
    .set_language(
        &LANG::Cpp
            .get_tree_sitter_language()
            .expect("cpp feature enabled"),
    )
    .expect("cpp grammar pinned to a compatible version");
let tree = parser.parse(source, None).expect("parser has a language set");
let root = Node(tree.root_node());

// Dump the AST from the first line of code in a file to the last one
dump_node(source, &root, -1, None, None).unwrap();
